“…Experimental results revealed that a lower cutting speed helps prevent the fibers from failure during forming and morphological defects. In Tseng's work [214], metal foams were used as flow distributors in the PEMFCs which outperformed the PEM fuel cells with conventional flow channels. Yuan et al [215] reported that metal wire mesh was a new way to create porous structure.…”

Fuel cells are the most clean and efficient power source for vehicles. In particular, proton exchange membrane fuel cells (PEMFCs) are the most promising candidate for automobile applications due to their rapid start-up and low-temperature operation. Through extensive global research efforts in the latest decade, the performance of PEMFCs, including energy efficiency, volumetric and mass power density, and low temperature startup ability, have achieved significant breakthroughs. In 2014, fuel cell powered vehicles were introduced into the market by several prominent vehicle companies. However, the low durability and high cost of PEMFC systems are still the main obstacles for large-scale industrialization of this technology. The key materials and components used in PEMFCs greatly affect their durability and cost. In this review, the technical progress of key materials and components for PEMFCs has been summarized and critically discussed, including topics such as the membrane, catalyst layer, gas diffusion layer, and bipolar plate. The development of high-durability processing technologies is also introduced. Finally, this review is concluded with personal perspectives on the future research directions of this area.

“…It produces more electricity per mass of fuel than any other non-nuclear method of power production. [4] One of the most important and effective elements in the improvement of efficiency and power density of PEMFC are the flow field plates. These components supply fuel and oxidants, remove generated water, collect produced current and provide mechanical support for the brittle membrane electrode assembly in fuel cell stack [5].…”

Abstract.One of the most important and effective elements in the improvement of efficiency and power density of proton Exchange membrane fuel cells (PEMFC) are the flow field plates. The flow field plate design and its pattern considerably affect the effectiveness of mass transport as well as electrochemical reactions inside the cell. A goal of the flow field plate configuration is to ensure a low pressure drop over all the channels in a cell or over all the cells in a stack. As a result, the aim of this research was use biological inspiration to improve the anode flow hydrogen area without improve the pressure loss in a parallel flow field plate (PFFP), by inserting fractals in a classic PFFP design. The results showed that, fractals can increase the hydrogen flow area without improve the pressure loss and repeat the PFFP fluid dynamic behavior at smaller scales in the same plate.

“…The channels-based bipolar plates have common drawbacks such as; large pressure losses, high cost of manufacturing and low mechanical strength; which increase the weight and volume of the fuel cell. In addition, the flow channels can cause unequal distribution of the electrochemical reactions which lead to irregular utilisation of the catalyst [15]. As an alternative to channels-based BP, Open Pore Cellular Foam (OPCF) metallic materials was used as bipolar plates and exhibited several key advantages such as better gas flow through the fuel cell, lower pressure drop from inlet to outlet and lower manufacturing cost [15]- [21].…”

Open Pore Cellular Foam (OPCF) has received increased attention for use in Proton Exchange Membrane (PEM) fuel cells as a flow plate due to some advantages offered by the material, including better gas flow, lower pressure drop and low electrical resistance.In the present study, a novel design for an air-breathing PEM (ABPEM) fuel cell, which allows air convection from the surrounding atmosphere, using OPCF as a flow distributor has been developed. The developed fuel cell has been compared with one that uses a normal serpentine flow plate, demonstrating better performance.A comparative analysis of the performance of an ABPEM and pressurised air PEM (PAPEM) fuel cell is conducted and poor water management behaviour was observed for the ABPEM design.Thereafter, a PTFE coating has been applied to the OPCF with contact angle and electrochemical polarisation tests conducted to assess the capability of the coating to enhance the hydrophobicity and corrosion protection of metallic OPCF in the PEM fuel cell environment. The results showed that the ABPEM fuel cell with PTFE coated OPCF had a better performance than that with uncoated OPCF.Finally, OPCF was employed to build an ABPEM fuel cell stack where the performance, advantages and limitations of this stack are discussed in this paper.
